'Applicatidn filed Decemberfi, 1884. (No model.)

To all whom it may concern.-

Be it known that I, JosnrirP. BUoKrNe. HAM,-a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvcments in Boxes, of which the following is a specification. 1

My invention relates to paper tubes or boxes, and more particularly to that class which are adapted to be folded flat for transportation and storage, and opened to receive and hold the contents; and it has for its object to improve the construction of such tubes and cases, and to render them stronger and more durable without materially increasing their cost; and to these ends my invention consists, primarily, in a folding re-enforc'edtube constructed as more particularlyhereinafter specifled, and, secondly, in such a tube having closing end pieces. I

Referring to-the accompanying drawings, forming part of this specification, Figure l is a perspective view of my improved tube. Fig. 2 is amend View of the tube folded fiat. Fig. 3 is a crosssection of the tube. Fig. 4 is a cross-section of a modified form of tube. Fig. 51s perspective of the tube, showing one form of end-closing pieces. Fig. 6 is a per spective showing the end closed.

It is desirable in constructing tubes or casesof the class mentioned to have them sufliciently. strong to resist any ordinary pressure or blow without breaking or giving way-soas to allow the contents thereof to be injured, and this has necessitated the use of comparatively heavy paper or board; and as it is also desirable to have the outside of the tube present a finished appearance and be smooth for the reception of sary to use a good quality of stock, which is expensive, or to construct the tube of a. poorer quality of stock and cover it with a thin, fine quality of material. Both of these modes of construction have their advantages and disadvantages, and it is the object of my invention to produce a tube that shall embody the for mer and avoid the latter, and at the same time be inexpensive to manufacture. I takea rectangular piece of stock, which may be Manila atube, A, of any shape, a square one being paper, card-board, or similar-material which has a smooth outer surface, and form 1t into shown in the drawings, and re-euforce the sides of the tubes with strips B, of heavier and cheaper material, by securing the strips to said sides by paste or glue, leaving a space, C, be-

folded, as shown in Fig. 2, for transportation orstorage. With some classes of material the overlapping pieces forming the bottom D, Fig. 4., for instance, may be made substantially of the same 'sizeas the top, and by securing them.

together they will form a sufficiently rigid portion of the tube; but when the outer material short and is secured tothe bottom flap, and a lie-enforcing piece, D, is applied, as in the sides and'top of the tube, as shown in Fig. 3. It will-thus be seen that I am able to produce a tube that is exceedingly strong and rigid when extended, and can be readily folded and packed,wliile it is comparatively inexpensive,

as there is no waste of material, the several stance, in corset-boxes and the 1ike-and in. Fig. 5 I have shown a means for closing tne ends which is simple and effective. An end piece, E, having projections or ends 6 8 made of the same material asthe outside of the box and re-enforced by pieces of cheaper material, b b has one of the ends, as e, secured between the bottom side, D, of the box and the reed force pieces D, and the otherend, e, is adapted tween the edges of the strips for the foldinglines of the tube, so that it can be readily to tuck into the end of the tube, the edges f f fitting into recesses or slots made by cutting away'a portion of the side re-enforcing pieces,

as shown at dottedlines g g.

In order torelieve the pressure of the contents of the bog: -'upon the end piece and to prevent the same from being forced out, the outer portion of the box A has pro ect ng flaps F F on its sides not re-enforced, which are folded inwardly before the tucking-flap 1s 5 is too light for such construction, or of afiner quality, the overlapping flap or edge (I is made fixed in its closing position, and are covered by the-end portion, E, when the-box is closed. This end-e1osing piece does not in any way interfere with the folding of thetube when it is out, and at the same time assists naterially in sustaining the tube in its upright position when closed. A f

' It is 'understood that other forms and constructions of closing-pieces can be used with my improved tube without affecting that part of my invention. l y

What I claim is 1. A folding reenforced paper tube consisting of an outer piece of material joined at itsedges to form a tube, and strips of re-enforcing materiel seeured to each of the inner sides, leaving spaces between their contiguous edges of a width sufficient to form the edge folds and. to permit the tube to be folded flat, substantially as described.

'2; The combination, with a re-enforeed tube consisting of an outer piece of material having re-enforcing strips secured to the sides, and having the flaps F extending beyond the re enforced portions, ofend pieces,E, having projections, one of which is secured between the outer and the re-enforcingpiece, and the other tially as described.

In testimony whereof I have signed my name to this speeification in the presence of two subscribing witnesses.
